Overview

Spectrum 5 combines several forms of magnesium, including citrate, glycinate, hydroxide and malate, with 72 trace minerals sourced from Irish sea water, dosed at 500mg per serving across 60 capsules and marketed for sleep support.

Blending multiple magnesium forms in one capsule is meant to combine how each type behaves, since forms like glycinate and citrate are generally handled differently by the body than hydroxide. The listing states the product is made in the USA, third party tested and GMP certified, which are checkable manufacturing claims rather than marketing language. The attribute data cuts off before naming the fifth magnesium form in the 5-in-1 blend, so it is not repeated here.

  • 500mg per serving
  • 5-in-1 magnesium blend
  • 72 trace minerals, Irish sea sourced
  • Third party tested, GMP certified, made in USA

Who it's for

Fits someone who wants a broad magnesium blend plus trace minerals in a single capsule rather than a single-form product like magnesium glycinate alone. Less suited to anyone who wants to dose one specific magnesium form for a targeted reason, since this is a mixed blend.

Pros and cons

Pros
  • Combines multiple magnesium forms in one capsule
  • Includes 72 trace minerals from sea-sourced material
  • Third party tested and GMP certified
  • Made in USA
Cons
  • Fifth magnesium form isn't fully specified in the data
  • 500mg serving is a blended total, not a single form dose

Performance notes

Different magnesium forms are absorbed and tolerated differently, so combining citrate, glycinate, hydroxide and malate in one formula is intended to spread that variability across the blend rather than rely on a single form. The Irish sea sourced trace minerals add a broader mineral profile alongside the magnesium itself. Third party testing and GMP certification, as stated in the listing, point to manufacturing oversight beyond the ingredient list.
